New orchid deception found: wearing the scent of hornet's prey
Orchids are famous for their deceptions. Most of those with nothing of value to offer their pollinators lure them instead with the scents of more rewarding flowers or potential mates. Now, a report published online on Aug. 6 in Current Biology, a Cell Press publication, reveals for the first time that a species of orchid, which lives on the Chinese island of Hainan, fools its hornet pollinator by issuing a chemical that honeybees use to send an alarm.

Calcium -- the secret to honeybees' memory
Long-term memory formation in honeybees is instigated by a calcium ion cascade. Researchers writing in the open-access journal BMC Biology have shown that calcium acts as a switch between short- and long-term storage of learned information. (2009-06-15)

A cure for honey bee colony collapse?
For the first time, scientists have isolated the parasite Nosema ceranae (Microsporidia) from professional apiaries suffering from honey bee colony depopulation syndrome. They then went on to treat the infection with complete success. (2009-04-14)

Flight of the bumble (and honey) bee
Honeybees and bumble bees are predictable in the way they move among flowers, typically moving directly from one to another in the same row of plants. The bees' flight paths affect their ability to hunt for pollen and generate (2009-03-20)

New insight into how bees see
New research from Monash University bee researcher Adrian Dyer could lead to improved artificial intelligence systems and computer programs for facial recognition. (2009-01-22)

Honeybees succumb to cocaine's allure
Cocaine is highly addictive for humans and no insects have been shown to experience the same pleasure from the drug. However it occurred to Gene Robinson and Andrew Barron that honeybees may be susceptible, because they are also driven by rewards. They tested this idea and found that foraging honeybees waggledance much more enthusiastically after a dose of the drug. They seem to experience the same addictive pleasures as humans. (2008-12-23)

Honeybees as plant 'bodyguards'
Honeybees are important to plants for reasons that go beyond pollination, according to a new study published in the Dec. 23 issue of Current Biology, a Cell Press publication. The insects' buzz also defends plants against the caterpillars that would otherwise munch on them undisturbed. (2008-12-22)

Bee smart, bee healthy
Bumblebee colonies which are fast learners are also better able to fight off infection, according to scientists from Queen Mary, University of London and the University of Leicester. (2008-10-30)

Remembrance of tussles past: paper wasps show surprisingly strong memory for previous encounters
With brains less than a millionth the size of humans', paper wasps hardly seem like mental giants. But new research at the University of Michigan shows that these insects can remember individuals for at least a week, even after meeting and interacting with many other wasps in the meantime. (2008-09-22)

Giant honeybees use Mexican waves to repel predatory wasps
In a new study published in the journal PLoS ONE this week, researchers at the University of Graz, Austria, and the Royal Botanic Gardens Kew, UK, report the finding that shimmering -- a remarkable capacity of rapid communication in giant honeybees -- acts as a defensive mechanism, which repels predatory hornets, forcing them to hunt free-flying bees, further afield, rather than foraging bees directly from the honeybee nest. (2008-09-09)

Saving our bees
The undisputed queen of animal pollinators is the bee, whose daily flights aid in the reproduction of more than half of the world's flowering plants. In recent years, however, an unprecedented decline in bee populations has placed the health of ecosystems an crops in peril. In an oral session at the ESA Annual Meeting, a group of scientists will explore the problem of bee habitat loss to determine what can be done to preserve bees in their native habitats. (2008-08-04)

Memory in honeybees: What the right and left antenna tell the left and right brain
The idea that all vertebrate species, even nonhuman ones without any linguistic skills, have an asymmetric brain seems to be finally accepted. Now brain lateralization has been extended beyond the class Vertebrata. Insects, with their nervous system so different from that of vertebrates, are also (2008-06-03)

Honeybee dance breaks down cultural barrier

Ecologists tease out private lives of plants and their pollinators
The quality of pollen a plant produces is closely tied to its sexual habits, ecologists have discovered. As well as helping explain the evolution of such intimate relationships between plants and pollinators, the study -- one of the first of its kind and published online in the British Ecological Society's journal Functional Ecology -- also helps explain the recent dramatic decline in certain bumblebee species found in the shrinking areas of species-rich chalk grasslands and hay meadows across Northern Europe. (2008-05-05)

Bees disease -- 1 step closer to finding a cure
Scientists in Germany have discovered a new mechanism of infection for the most fatal bee disease. American Foulbrood is the only infectious disease which can kill entire colonies of bees.

Warning from Asian bees
Four swarms of Asian bees found in Cairns have been cleared of carrying the dreaded Varroa destructor mite, but the intruders themselves could pose the beginning of a serious threat to Australian honey bee populations. (2007-06-15)

The bee that would be queen
A team of researchers from Arizona State University, Purdue University and the Norwegian University of Life Sciences has discovered evidence that honeybees have adopted a phylogenetically old molecular cascade -- TOR (target of rapamycin), linked to nutrient and energy sensing -- and put it to use in caste development. They found that queen-fate can be blocked, and that workers develop, when TOR activity is reduced during development. (2007-06-05)

Hives ferment a yeasty brew, attract beetle pest
The honeybee's alarm signal may not only bring help, but also attract the small hive beetle. Now, an international team of researchers has found that small hive beetles can detect some alarm pheromones at levels below that detected by honeybees. (2007-05-16)

Survival of the rarest: Fruit flies shed light on the evolution of behavior
New study reveals why it's beneficial to stand out in nature. (2007-05-09)

Detecting poisons in nectar is an odour-ous task for honeybees
Though many spring flowers have bright advertisements offering sweet rewards to honeybees, some common flowers have not-so-sweet or even toxic nectars. Why plants would try to poison the honeybees they wish to attract is a scientific mystery. Can honeybees learn whether nectar contains toxins, and does this influence their ability as pollinators? Dr. Geraldine Wright from Newcastle University will present data on how toxins in nectar affect a honeybee's willingness to eat floral nectar. (2007-03-31)

The social life of honeybees coordinated by a single gene
vitellogenin gene activity paces onset of foraging behavior in worker bees, demonstrating how coordinated control of multiple social life-history traits can originate via the pleiotropic effects of a single gene. (2007-03-05)

Honeydew honeys are better antioxidants than nectar honeys
A study of 36 Spanish honeys from different floral origins revealed that honeys generated by bees feeding on honeydew have greater antioxidant properties than those produced by bees feeding on nectar. The study is published in this month's edition of the Journal of the Science of Food and Agriculture. (2007-02-21)

A bio-inspired flying robot sheds light on insect piloting abilities
Insects and other flying animals are somehow able to maintain appropriate flying heights and execute controlled takeoffs and landings despite lacking the advantage of sophisticated instrumentation available to human aviators. By characterizing the behavior of a specially designed flying robot, researchers have now been able to test a theory that helps explain how visual cues are used by insects during flight to ensure appropriate distance from the ground. (2007-02-08)

Queen bee promiscuity boosts hive health
Though promiscuity may be risky behavior for humans, it's healthy for honeybees: Queen honeybees who indulge in sexual surfeits with multiple drones produce more disease-resistant colonies than monogamous monarchs, according to a new study. (2006-12-08)

There's much more to bees than honey
The findings from the Honey Bee Genome Sequencing Project are published today in (2006-10-25)

New behavior may use old genes
Though you may not be able to teach an old dog new tricks, ASU researchers have found that evolution may have taught old genes new tricks in the development of social behavior in honeybees. The genetic basis of social behavior is being deciphered through the efforts of ASU researchers and their work with the honeybee, Apis mellifera. (2006-10-25)

Origins, spread of honeybees determined
